Theory of ultrafast optical nonlinearities of uniaxially strained quantum wells

摘要

Abstract: A theoretical study of ultrafast many-body effects in anisotropic semiconductors is presented. Signatures of coherent exciton-exciton interactions are identified in polarization traces in Poincare's cartesian complex plane of polarization which is used to visualize the differential polarization rotation of ultrashort light pulses due to excitons in uniaxially strained quantum wells. !16
